can I force the reuse of an OID? for instance, if I were to get the
map'ngs for those toast files, and then 'drop' the old database (I've got
several backups of it already), can I insert those records into pg_class,
with the proper OID? Then again, OIDs don't have to be unique across
databsaes, do they? they are only serial ... so I should be able to just
add those records into the new database, no?
